Handpiece won't go into cooling

I have a regular cutera xeo, that you can plug a prowave handpiece in. The prowave handpiece wont go into cooling, but the same handpiece will cool on a different system. What seems to be the problem? Any insight would be helpful.

Hello Laser J,

Are you actually getting any kind of error code when you try to enter into cooling? Are there any indicators your system is giving at all?

I'm not getting any error codes. I put the limelight into "ready" but the tip won't cool so all i get is the thermometer icon.

Sounds like you have a TEC (Thermo Electric Cooler) issue. They go bad over time and could require replacement. Another possibility is that the heatsink compound is old and allow for good heat tranfer. But either way, I believe the issue to be TEC related.

Would you know where that is located on a Xeo? Is it an entire TEC circuit that needs to be replaced, or just a single component/ part?

The possibility exists that the error is due to the circuitry driving the TEC, but typically, it's the actual part. The part(s) can be found mounted directly onto the crystal light guide.

Excuse me, I am a little new to this industry, and not totally famiiliar with the laser. The error is not with the handpiece nor with the YAG. I do not know what you are refering to as the "crystal light guide". Is the TEC on a board? If so which one. If not, where in the laser could I find this TEC.

Thanks for your help
